ROOFING-TOOL.

SPECIFICATION forming part of Letters Patent No. 620,426 dated February28, 1899.

Application filed November 25 1898. Serial No. 697,384. (No model.)

To aZZ whmn it may concern.-

Be it known that I, ALBERT DANZER, of Hagerstown, in the county ofWashington and State of Maryland, have invented a new and usefulImprovement in Roofing-Tools, of which the following is a specification.

In the application of tin roofing to buildings it is customary to firstsolder the sheets of tin together to form long strips and then turn upboth edges of each strip to form standing flanges. Then the tin isanchored down to the wooden sheathing of the roof by small clips orhooks of tin hooked over the top of the standing flange and nailed downinto the sheathing. Then when the next adjacent strip of tin is laid oneof its standing flanges is made to abut closely against the standingflange that has been thus tied down by nailing, and the two abuttingflanges and inclosed hook-clips are next by a special tool seamed androlled over to lock them together, thus making the ordinary form ofstanding-flange roof. In this operation the nailing of the numeroushook-clips down into the sheathing is not only a tedious operation, butas the nails have to be held in the fingers while being driven-throughthe tin hookclips the work is very hard on the fingers, frequentlyinvolving the mashing or bruising of the same and the partial disablingof the hand of the workman.

My invention is designed to provide a special tool for nailing down thehook-clips in such a manner as to relieve the hands-of all damage and toenable the work to be done in a more expeditious and secure manner; andto this end it consists in the peculiar construction and arrangement ofthe tool, which I will now proceed to describe with reference to theaccompanying drawings, in which Figure 1 is a side View of the tool;Fig. 2, a longitudinal section of the same. Fig. 3 is a partial view ofthe tool, showingits first application to the hook-clip. Fig. 4 is asectional view showing the operation of driving the nail. Fig. 5 is aview of the work as done by my tool and ready to receive theseaming-tool, and Fig. 6 is a perspective view of one of the hook-shapedclips.

Referring to Figs. 3 to 6, S is the wooden sheathing of a roof, and T T'are two adjacent strips of tin formed with standing flanges f f Afterthe strip T is laid and before T is applied a clip 0, Fig. 6, is hookedover the top of the standing flange and the bottom or horizontal end issecured by anail n to the sheathing. This is the work which my tool isintended to perform. This being done, another tin strip T, Fig. 5, islaid with its flange f adjacent to and projecting a little above andabutting against the flange f and clip 0, and the top edges of flangesff and clip 0 between them are then turned over by the seamer to closethe seam, which is now held down to the sheathing by the anchorage ofthe nail n in the clip 0.

My tool consists of two parts. The steel driving-rod A, with weightedhandle a, of solid iron, shrunk on the rod, forms one part, and theother part consists of a hollow shank B, with a hole through itlongitudinally, in which the driving-rod A plays up and downand fitsclosely but loosely. This shank B has at its lower end a rectangular endI), with a fiat end face, through which the driverchannel opens. Atpoints above the lower end, a distance about equal to the standingflanges f f, there are formed obliquelydrooping lips I) b, one oneachside, and just above these there is soldered or brazed a small hopper orchute 0, whose bottom communicates with a passage-way leading into thechannel-way of the driver. This chute receives the nails and guides themto the central passage-way. A little above this chute there is formed onthe tubular shank a swelled shoulder 19*, on which rests a metal ferruled. Above this is located a wooden handle D, and above the handle D is arecessed metal collar e, which is riveted'or swaged tightly to thetubular shank by slightly expanding the upper end of the latter withinthe collar. This causes the wooden handle to be tightly held on thetubular shank between the c0l= lar e and ferrule d. The shank B, withits head I), lips I) b, and shoulder b all formed in one piece ofmalleable cast-iron, is then bored or drilled to form the longitudinalchannel.

In making use of this tool it. is applied to the clip on the standingscam in a slightlyinolined position, as shown in Fig. 3, and is thenswung over to a vertical position, as indicated by the arrow. Thepurpose of this movement is to cause the lower end I) to bend .puts theflanges ff in proper juxtaposition for seaming, and also gives a thinnerand stronger seam and a more direct tie of the seam to the roof. Afterthe tool is brought into the vertical position, as shown in Fig. 4:, thedriver A is elevated and the nail ndrops from the chute 0 down onto theclip, as in Fig. 4, and the weighted driver being then brought down thenail pierces the clip end and is sunken into the sheathing, as shown indotted lines in Fig. at and full lines in Fig. 5.

In constructing the driver A it is made a little longer than the hollowshank, as shown in Fig. 2. This is for the purpose of cansing the lowerend of the driver to take up against the solid bearing of the sheathingbefore the weighted handle a strikes the top of the hollow shank, thusavoiding the battering of the latter.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

1. A nail-driving tool for metal roofing, comprisinga tubular shankportion having near its lower end one or more downwardlyprojecting lipsadapted to rest upon the top of the standing flange of theroofing-sheet,

a chute leading into the central passage-Way of the shank, and areciprocating driver playing in said passage-Way substantially as andfor the purpose described.

2. A nail-driving tool for metal roofing, comprising a tubular shankportion, with a rectangular lower end and downwardly-projecting lips oneach side of the same adapted to rest upon the standing flange of theroofin g-sheets, a nail-chute attached to the side of the shank andopening into its central passage-Way, and a reciprocating driver playingin said passage-Way substantially as and for the purpose described.

8. A nail-driving tool for metal roofing, comprising a tubular shank Bwith oblique downwardly-projecting lips I) b, rectangular end I), andshoulder b all formed in one piece, a chute 0 attached to the side ofthe shank and communicating with the passage-way Within, the ferrule d,handle D, and collar e swaged upon the tubular end of the shank abovethe handle, and a reciprocating and weighted driver playing Within thetubular shank substantially as and for the purpose described.
